Mr Pejic opened the show for Rosa Clara at Barcelona Bridal Week 2012 in an ethereal white gown, with a thin ribbon tied under the bust and gauzy layers of skirt revealing his platform shoes.

He later made a second appearance in a figure-flattering, floor-length textured dress, topped with a matching button-up, cap-sleeve jacket.

Both dresses were far more traditional than the one he previously wore as the star bride of the Jean Paul Gaultier Haute Couture Spring 2011 Fashion Show.

The US size 2-4, the 6ft 1in model has fast become one of the most talked about figures in the fashion world with his long platinum locks, icy blue eyes and delicate, slender body, and is the only top-tier fashion model who can walk down the runway as either a man or a woman.

'He's just this beautiful thing that everyone wants a piece of,' says stylist Ken Anderson, who dressed Mr Pejic for a German magazine cover.

Though he isn't trying to be a woman, many in the transgender community have already claimed Mr Pejic as their own and last year, the gay and lesbian magazine Out named him 'stylemaker of the year' putting him on its cover wearing a bridal veil and flowers in his hair.

Earlier this year Jean Paul Gaultier also signed him as the face of its first men's fragrance since its iconic torso-shaped Le Male.

The opportunity will not only give the model a change from flaunting his femininity on the catwalks of women's couture, but will provide a stark contrast to traditional men's perfume campaigns of the past.

No one yet knows whether he'll be appearing as a man or woman.

But life hasn't always been so easy or glamorous. Born in Bosnia, Mr Pejic spent much of his childhood living in a Serbian refugee camp before his family fled the country for Australia. He was discovered by a talent scout while working at a McDonald's as a teenager.

From an early age, he exhibited qualities thought of as traditionally feminine, for instance, preferring Barbie dolls over toy cars. As a teenager, he often hung out with girls and was once busted for stealing make-up from a drugstore.

Mr Pejic says acceptance from his friends and family made him comfortable in his own skin.

'I'm lucky in that sense,' he says. 'If I had big muscles and were hairy with a beard, I might not be comfortable with that.'

He follows in the footsteps of Mischa Barton who previously wore a silk organza Rosa Clara gown on the Bridal Week runway in 2010.
